Good news: I can't reproduce the bug in Chromium "Version 67.0.3386.0 (Official Build) (64-bit)".

Status: Untriaged (was: Unconfirmed)
Able to reproduce this issue on reported version 65.0.3325.181 using HIDPI windows machine when hardware acceleration is disabled. Issue is not reproducible on latest beta 66.0.3359.81 and latest canary 67.0.3394.0.

As we don't have any stable refresh of M-65, and stable is moving to M-66 tentatively in two to three weeks.
@Reporter: Please check the issue on latest beta and let us know if the issue is fixed there. You can download beta build from https://www.chromium.org/getting-involved/dev-channel.

Thanks!
